Abstract
We present our results for the bottomonium spectrum with self energy corrections. The bare masses used in the calculation are computed within Godfrey and Isgur's relativized quark model. We also discuss our results for the open bottom strong decay widths of higher bottomonia in the 3 P0 pair-creation model.
Highlights
The quark model (QM) [1,2,3,4,5,6,7,8,9,10,11,12,13,14] is very successful in reproducing the behavior of observables such as the spectrum and the magnetic moments, but it neglects pair-creation effects

We discuss an application of the unquenched quark model (UQM) [34,35,36, 39,40,41] to the calculation of the bottomonium spectrum with self energies corrections [36]
Summary
The quark model (QM) [1,2,3,4,5,6,7,8,9,10,11,12,13,14] (see Refs. [15, 16]) is very successful in reproducing the behavior of observables such as the spectrum and the magnetic moments, but it neglects pair-creation effects. [15, 16]) is very successful in reproducing the behavior of observables such as the spectrum and the magnetic moments, but it neglects pair-creation effects. The simplest model, describing this phenomenon, is the 3P0 pair-creation one, in all its possible variants [42,43,44,45,46,47] In this contribution, we discuss an application of the unquenched quark model (UQM) [34,35,36, 39,40,41] to the calculation of the bottomonium spectrum with self energies corrections [36]. We briefly discuss our results for the strong decay widths of higher bottomonia [36], computed within a modified version of the 3P0 paircreation model [34,35,36]
